Expanded Graphite Gland Packing

Expanded Graphite Gland Packing

Expanded graphite packing are braided from flexible graphite yarns. It has a very low friction, good thermal and chemical resistance and high elasticity.

Flexible Graphite Packing with Corrosion Inhibitor. Corrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box.

Having much high pressure tightness and much stable performances, applicable for static seal packing under high temperature and pressure.

Key Features

Flexible graphite packing is a multi-service packing capable of a wide variety of uses throughout a plant.

It can be used in valves, pumps, expansion joints, mixers and agitators in high-pressure and temperature.

Effective sealing is vital.

Reinforced with glass fiber: high strength, lower cost

Good thermal and chemical resistance and high elasticity.

High pressure graphite rope is mainly woven with various reinforced fibers, metal wire (steel wire, copper wire, nickel wire) and other reinforced graphite wire.

Applications

Applicable equipment pumps, valves and grooves: braided from pure extended flexible graphite. It is self-lubricating, chemically inert and thermal conductive

Materials are applied to air, ammonia, chemicals, corrosive agents, gas, oils, paper, paints, solvents, liquids, water, steam, boiler feed and condensates

Applicable mediums: With a few strong oxidation media, sealed hot water, high temperature, high pressure, water vapor, heat exchange media, hydrogen, ammonia, organic solvents, hydrocarbons, extreme cold liquids, etc.
